From what I saw, you were interpreting Schere's post as passive-aggressively referring to an incident with you, stuff like this:
And since we are about more honest and diplomatic approaches, may I suggest that you directly call me for using the term you mention instead of remaining vague and passive-aggressive like that ? This, too, is difficult to cope with, and I hope you will understand. Just tell me what you think of it, with respect and calm words as you are able to do (shown here), instead of beating around the bush. This only helps people feel targeted and only gets frustrating/unto the nerves of the other.
very condescending and 'looking down your nose' I'm not saying that was the intent behind your words, but that was the meaning I got off reading them, was that it seemed to be putting down or trying to put down Schere for their post, based on the fact that you felt that Schere's post was an attack on you specifically.
However, Schere's post wasn't actually referring to you, if it was, she would have fallen victim to the same rule you have here. You interpreted something as an attack on you and responded in kind. In the future, maybe try reporting the post if you feel that's the case, instead of responding to it.
Just my thoughts, I'm not a mod here.
